My commentary:
The road noise is unaccaptable for a professional demonstration by a large organization like ACE, I would expect it from garage guys work out, not someone I pay money to make these videos. However the movements are correct and those are excellent ab exercises for deconditioned people. You can use them to warm up, and/or part of cool down. I use elbow to knee "air bike" warm up in the morning. I would skip plank for reverse hyper extension to warm up the low back.

The best part of this video is how he demonstrated the lying elbow to knee/air bike, that was pretty much perfect. My research shows this to be a big bang for buck exercise.
